Abstract :
Very fast voltage rise curves due to gap discharge were examined to discuss an EMI source. The measurement system consists of a distributed constant line system, because the voltage transients were very rapid. A characteristic of the gap electrode, which has a matched impedance for the distributed constant line system, was investigated in the frequency range below 5 GHz. The voltages of the power source in the experiment were 510 V and 800 V because Paschen´s law holds its stability in the air condition. It was confirmed that the measurement method enables one to measure high speed voltage rise curves of about 100 ps
